This invention relates to type casting machines of the kind capable ofuse for the production for stock of type pieces bearing each a singlecharacter or representation only, a matrix having as many forms as themaximum number of characters required to be produced being movable intwo dimensions to bring individual forms one at a time into position forthe casting of a predetermined number of type pieces successivelytherein, the casting being interrupted with the termination of thecasting of each set of type pieces of like character (i. e. in one form)and said pieces being fed as they are cast into a line channel in whichsome at least (according to the number in a set) of said pieces remainat the termination of a corresponding casting operation, pieces which donot remain in said channel simply falling one by one by gravity as theyreach the end of the channel. The usual line hook, which functions atthe termination of each casting operation, does not move the morerecently cast pieces far enough along the line channel to enable them tofall clear of the latter and, therefore, not only the placing of thesets of type characters in the corresponding or appropriate compartmentsof the usual type cases or compositors trays, but also the removal ofthose pieces of each set which remain in the line channel at thetermination of that casting operation which produced them has heretoforebeen efiected manually.

As is well known in machines of this kind, the positioning of the matrixfor the casting of individual type characters and the duration of eachcasting operation are determined by a common automatic control whichoperates according, for example, to perforations formed in a travellingpaper roll by the operation of a keyboard.

The invention has for an object to avoid handling or manipulation of thetype pieces.

To this end and in accordance with the inven tion, at the termination ofthe casting of each set of type characters a member under the commonautomatic control cooperates with the type character last formed andshifts all the characters in the line channel clear thereof.

Also according to the invention, delivery means under the commonautomatic control cause each set of type characters to be delivered intothe corresponding or appropriate compartment of a compositors tray.

For causing delivery of type characters into the corresponding orappropriate compartments of a compositors tray, a chute extendingdownwardly from where the type characters leave the line channel, or thelower part of such chute may be movable to bring the lower end of thechute into positions registering with the compartments, respectively, ofa compositors tray located therebeloW.

Again, for causing delivery of type characters her and in spacing attheir lower ends with a single row of compartments in a compositors traymay be movable under the common automatic control to register withseveral rows, one at a time, of the tray, the branches of the chutehaving shutters operating under the common automatic control to open onebranch. only at a time.

The invention is illustrated by the accompanying diagrammatic drawingsof which Figure 1 is a plan view of the arrangement and operationaccording to one form of the invention of a member for shifting typepieces clear of the line channel (part being schematic and drawn to areduced scale), Figures 2 and 3 being sectional views on the line 22 ofFigure l and 33 of Figure 2, respectively;

Figures 12 and 13 are diagrams showing in side elevation further formsof delivery means according to the invention; whilst Figures 14 and 15show to a reduced scale an arrangement for use with a compositors trayhaving compartments of several sizes.

Referring first to Figures 1, 2 and 3, there is indicated at 2| theusual table of an existing machine having upstanding ribs 22 definingtherebetween the line channel, indicated at 23, the usual line hookbeing indicated at 24 in the position occupied thereby at the end of itsoperative stroke. According to the invention, that normally displaceablepart of one rib 22 which is indicated by broken lines (Figure 1) isremoved or moved out of position and there is journalled in the table 2ia vertical spindle 25 having fast upon its upper end an arm 25 fromwhich a pin 2'! extends through a slot 28 in a block 29 to be receivedin a bore in an auxiliary line hook 30 pivotally mounted on the blockat3|. The auxiliary line hook 30, see Figure 2, is comprised by upperandlower members disposed on opposite sides of the block 29 to engage withatype character at both the upper and lower parts of the latter; part ofthe arcuate guide 32 being cut away at its under side to allow thelowerm'ember of said auxiliary line hook 35 to move between said arcuateguide 32 and the upper surface of the table 2!. To the upper surface ofthe table 2! there are affixed the arcuate guide 32 and a plate 33 whichtogether provide a curved extension 35 of the line channel 23.Reciprocating motion is imparted to the spindle 25 through the medium ofa crank 35 and a pneumatic cylinder and piston, indicated at 35, thesupply of air to which is controlled by a valve 31 operated by anadditional cam 38 on the usual camv disc 39 whereby motion is impartedto the, normal line hook 25. It will be seen that when the arm 25 movesin a clockwise direction the pin 2'! thereof will travel to one end ofthe slot 28 in the block 29, so rocking the auxiliary line hook 30 aboutits pivot 3! clear of the line channel extension 34 and will then carrywith it the line hook and the block 25 to the end of the clockwisestroke. Similarly, during anticlockwise movement the lever 25 will firstmove to carry the pin 2'! thereof to the other end of the slot 28 in theblock 29 so rocking the auxiliary line hook about its pivot 3! intoposition across the curved line channel extension 34 and will then movesaid block 21 and line hook 30 bodily therewith. To ensure such rockingof the lever 35 at thecommencement of the clockwise and anticlockwisestrokes, the block 29 (see Figures 2 and 3) has one margin shaped, asindicated at 40, to co-operate under the influence of a leaf spring 4|with undercut walls of a recess 52 in the arcuate guide 32; frictionalco-operation of the block 29 with said walls ensuring that the block 23shall not move until the pin 21 has reachedone end or the other of theslot 28. At the outlet end of the curved line channel extension 34 thetable 21 is formed with a delivery opening 43 through which type pieces,indicatedat 44, fall upon leaving said extension 34, a delivery chuteextending downwardly from said opening 43, as indicated at 45. Thecurved guide 32 is formed throughout that part of its length opposite tothe plate 33 with a continuous projection 45 for engagement in the usualgrooves in the type pieces 53 to resist any tendency of the latter totilt during their passage along the curved line channel extension 34.The timing of the strokes It will be understood that the mechanism justdescribed is intended as a fitment to or modificaof the auxiliary linehook 353 is such that the auxiliary line hook 35 commences eachoperative or type delivering stroke as or immediately after the normalline hook 2d completes its operative stroke.

tion of an existing machine which as a rule, if not invariably, willhave insufiicient space below the table 2! at the point where the typepieces 44 enter the curved line channel extension 34 to accommodate adelivery chute such as 45. In order that the auxiliary line hook 30, thearm 26, block 29 and the arcuate guides 32 and 33 shall not interferewith the normal delivery mechanism of the machine when the latter isused for composing, said parts may either together comprise a readilyremovable unit, or they may be so mounted individually upon the table 2|as to bereadily removable therefrom. Also, if desired,

means may be provided for closing the delivery opening 43 in the table2|. I The outer curved wall of the curved extension 34 of the linechannel 23 ,may be adjustably and/or resiliently mounted so that thewidth of the curved channel extension 34 may be varied to suit typecharacters of different sizes. For this purpose the outer curved wallmayitself be deformable, e. g. formed from thin springymaterial.

It will also be seen that in some cases it may be possible, instead ofproviding an additional line hook such as 35, so to modify the mechanismoperating the normal line hook such as 24, that,

the operative stroke thereof may be increased so that it will remove allthe type characters from the normal line channel.

In the delivery mechanism shown in Figures 4 to 11, a carriage for acompositors tray is moved, each time the matrix of the machine is moved,to bring a corresponding compartment of a tray on the carriage int'oregister withithe place where type characters fall on leaving the linechannel,

for instance, in the case of the arrangement de scribed with referenceto Figures 1, 2 and 3, into register with the lower end of the chute 45.

Referring first to Figure 4, two sets of guide rails 5! and 52,respectively, disposed at rightangles to one another carry twotravelling frames 53 and 54 and serve together to support and to impartthe desired motion, to a carriage 55 for a compositors tray (notshown).Movement in steps is imparted pneumatically to the two frames 53 and 55,the frame 53 having associated'therewith two sets of cylinders andpistons 56 and the frame 54 having a single pair of cylinders andpistons 51. The frame 53 has a pair of racks 53 with which co-operateretractable plungers 59, and the frame 54 has a single rack 60 withwhich co-operates a single plunger 6|, said plungers 59 and GI servingpositively to locate the frames 53 and 54 in the various positionsoccupied thereby during delivery of type characters. a The cylinders 55and 5! are mounted upon a base plate 62 which also carries the two setsof rails 5| and 52,and in the case of the-frame 53 (see Figures and 6)each cylinder 56 has a piston rod 63 protruding therefrom which isconnected with one arm 64 of a bell crank lever 64, 65 which latter armis formed to engage the notches of the corresponding rack 58, said lever34, 65 being fulcrumed at 66 upon a block 6'! slidable on guide rails 68supported at their ends on the cylinders 56.

The pneumatic operation is such that the cylinders 55 at one side or theother only of the frame 53 function at a time to move said frame in onedirection or the other through a distance corresponding with thedistance between adjacent rows of compartments in a compositors tray inposition on the carriage 55, the stroke of each slide block 61 beinglimited in one direction by the mounting of the guide rods 68 on thecorresponding cylinder 59 and in the other direction by a fixed housing69 for the plunger 59 carried on the guide rods 68. The slidable block61 on which the bell crank lever M, 65 is mounted may be spring orfrictionally loaded to ensure proper or full engagement of said lever63, 65 with a notch of the rack 58 before the block 6! is shifted.

The plunger 59 extends downwardly from its housing 39 and when in thelocking position is spaced at its lower end from the base plate 62 by adistance only slightly greater than the depth or length of the teeth onthe rack 59, this downwardly extending part of the plunger 59 being inlost motion connection with corresponding ends of two levers III, II,I0, I! the arms it of which extend between flanges E2 on the plunger 59.The levers I9, H are fulcrumed about a common pivot l3 and the arms lIthereof extend over pneumatically operated plungers Hi (see Figure 6),the raising of either of which results in downward movement of the arm19 of the corresponding lever 70, TI into co-operation with the lowerflange E2 on the plunger 59 and therefore in re traction of the latterfrom the rack 59. Each lever 19, III has a pin it extending therefromover an axially slidable valve member 19 the head TI of which normallyco-operates with a seating E8 to shut off from a supply of compressedair (see Figure 9) connected with a port I9 from the cylinder 56 at thecorresponding side of the plunger 59 which cylinder has an inlet 89connected with the outlet SI of the valve. Each plunger 74 (as indicatedby dotted lines in Figure 5) is movable in a cylinder 82 having an inlet83 connected with the supply of air under pressure.

Admission of air to a cylinder 82 raises the corresponding plunger 14and depresses the arm I of the corresponding lever I9, H, the pin 15 ofwhich co-operates with the corresponding valve member 79 and depressesthe latter to place the corresponding cylinder into communication viathe inlet i9 with the above-mentioned air supply. The downwardly movingarm 19 also co-operates with the lower flange '12 on the plunger 59 andretracts the latter from the rack 58. As a result the corresponding bellcrank lever 64 is rocked about its fulcrum 69 to bring the arm 65thereof into co-operation with a notch of the rack 53 and then the slideblock Bl moves from the position shown into contact with the plungerhousing 69 carrying with it the rack 58 and frame 53 through acorresponding distance which is equal to the width of one cornpartmentof the tray (not shown). In order to ensure that movement as describedof one lever Ill, II shall retract the plunger 59 and yet open one onlyof the valves I9 the distance between the upper end of each valve member15 when closed and the pin I5 of the corresponding lever 79, H when inits normal position as shown, is greater than the distance between thelower end of the plunger 59 and the base plate 62.

The mechanism for imparting movement in steps to the frame 5 is as aboveindicated the same as that for moving the frame 53 except that only twocylinders 5's and a single rack 69 and plunger SI are employed. In thiscase (see Figures '7 and 8), the two cylinders 5! are mounted on thebase plate 62 with their piston rods 84 connected with a bell cranklever 85 fulcrumed at 86 upon a block 8! slidable, if desired, againstfrictional or spring resistance, on guide rods 88 between the mountingsof said rods 89 on the cylinders 51 and a fixed housing 99 carried bythe rods 88 for the plunger BI. Also the mechanism associated with theplunger SI is equivalent to but not precisely the same as the mechanismfor operating the plunger 59, two levers 99 extending in oppositedirections instead of alongside one. another as do the two levers I0, II. The levers 99 are forked at their ends (see Figure 8) and each has alaterally extending pin 9| which instead of co-operating directly with avalve member co-operates with one end of a further lever 92 which actsupon a valve member 93 at its other end. This valve member controls theconnection of the corresponding cylinder 5! with the source ofcompressed air in the same way as the valve member '56 controls theconnection of the cylinders 56 with said source. The pneumatic plungersfor actuating the levers 96 are indicated at as, the connection of theair supply thereto at 95, and the inlet and outlet for air past thevalve member 93 at 96 and 91, respectively, and the inlet for air to thecylinders 57 at 9B.

The operation of the mechanism described is controlled by the normal orexist-ing automatic control of the machine in which a paper strip,indicated at 99 in Figure 9 of the drawings, is fed continuously overthe open ends of a series of air pipes I99 to determine into which ofthese compressed air can enter from a common supply chest !9I. As iswell known there is as a rule a considerable number of such pipes 599but only five of these are utilized for the purposes of the invention,these five alone being shown in the drawing. Each of these five pipes istapped or branched, as indicated at I92, so that air entering itactuates or controls part of the mechanism according to the invention aswell as part of the machine normally actuated or controlled thereby.

It will be remembered that the supply of air to each of the cylinders 56and 51 is controlled by a corresponding valve E6 or 93, these valvesbeing in turn operated by pneumatic plungers I4 or 99. Each plunger M or94 receives air under pressure by which it is operated to open thecorresponding valve from the same source as the cylinders 55 and 57under the control of the corresponding one of a number of valves in achest I93, the two pneumatic plungers l4, actuation of which results inmovement of the carriage 53 in the one direction, being controlled bythe valve IM, and the other two plungers l4 being controlled by thevalve I05, whilst of the two plungers 94, one is controlled by a valveI96 and the other by a valve I97 in said chest I03. A further valve H39in the chest I93 serves to connect the inlet sides of the valves I94,35,196 and I9? with the air supply, indicated at I99, and all of thevalves IIl l, i95, I99 and I97 are operated by air reaching the chest WIaccording to apertures formed in the paper strip 99 passing over theopen ends of the pipes I99.

The valve chest IE3 is shown more clearly in Figures and 11. Each valveI94, I95, I06, I01 and I98 is in the form of a plunger and as shown inFigure ll. in the case of the valve I94 comprises a head IMA having astem I953 with which cooperates one end of a corresponding rocking leverHMC bearing at its other end upon a pneumatic plunger IMD raising ofwhich latter by air via the corresponding pipe H39 and branch I02 opensthe valve. Air outlet pipes from the valves I94, I95, I95 and IM areindicated in Figure 10 at IMX, IBEX, 506K, and IllIX and the inlet sidesof these valves are connected with one another by a bore H9 in the chestI93 and via a pipe II with the'outlet side IEiSX of the valve I98, the

inlet I08Y of which is connected with the air supply I09.

It will be seen that when the carriage 55 is stationary, for example,during the casting operation, air from the supply I09 is shut off fromthe cylinders 55 and 57 by the valves 16 and 93, respectively, and fromthe inlets of the valves I04, I05, I06 and I07 by the valve I08. At thetermination of a casting operation air from the chest IOI is allowed byan aperture in the paper strip 99 to open the valve 908 thus placing thevalves I04, I 05, I 06 and it? into communication with the air supplyI09, then, according as a compositors tray on the carriage 55 requiresto be moved in one or both dimensions to bring into position for thereception of type the compartment of the tray appropriate to thecharacters next to be cast, the appropriate valve or valves of the groupI04, I05, I06 and I0! is or are opened to efiect the necessary movementsteps of one or both of the frames 53 and 54 and thus of the carriage55.

Each of the pipes I00 which is branched for the purposes of the presentinvention will in general be one the passage of air through which alonewill not bring about any operative function of the machine as apart fromthe present invention, e. g. in moving the matrix, and further that pipeI00 which is tapped for the control of the valve I 08 will be one thepassage of air through which renders the machine incapable of casting.Not until air ceases to pass through this pipe will the next positioningof the matrix to determine which type character shall next be cast takeplace. Thus, it will be noted that the tapping of the pipes I00 apartfrom that leading to the valve I08 will in no way affect matrixpositioning or other operations of the machine because opening of anyone or more of the valves I04, I55, I05 and IIJI when the valve I08 isclosed is ineffective.

All the members which are shifted pneumatically according to theinvention are returned to their normal positions by springs which forthe sake of clearness are not shown in the drawings.

Means, not shown, may be provided for enabling any or all of the valvesI04, I05, I06, I01 and I08 to be operated at will manually.

The mechanism described with reference to Figures at to 11 is forimparting movement to a compositors tray beneath a fixed delivery outletfor type as indicated in the opening paragraphs of the specification.However, a compositors tray may in some cases remain stationary and anoutlet for type may be moved instead, by mechanism similar to, but oflighter construction than, that described with reference to saidfigures. For example, as shown in Figure 12, a chute such as 45 ofFigure 1 may have its lower end formed as indicated at IZI andterminating above a funnel-shaped type delivery member I22, the outletI23 of which corresponds in cross-sectional area with individualcompartments of a compositors tray indicated at I24, this funnel beingcarried by rollers I25 running in rails I26 extending in one dimensionand on a carriage I27 mounted for movement on rails I23 extending in theother dimension. It will be noted that in such an arrangement the intakeend of the delivery member I22 will be of the same shape and at least ofthe same size as the tray I24.

Again, as above indicated, a delivery chute such as 45 Figure 1 may feedthe type to a branched delivery chute at I29 (Figure 13) which latter asa whole is pivoted about an axis I30. The outlet orifices I3I of thebranched chute I29 are disposed in a straight line and correspond innumber with the number of compartments in a row of a compositors tray,indicated at I32, each branch being controlled by a pivoted shutter I33so that type entering the chute I29 can issue therefrom via one only ata time of the outlet orifices I3I to determine into which of thecompartments of a row type characters shall be fed for any castingoperation. The automatic control means in this case serves to bringabout the operation of the shutter I33 and also to bring about movementof the chute I 29 as a whole about its pivot I30 to bring the outletsI3I into register with the different rows of compartments of the trayI32. It will be seen from a consideration of Figure 13 that the shuttersI33 are so arranged that those in the lowermost row may be operatedsimultaneously as by a control rod I34 and that the intermediate pair ofshutters I33 also may be operated by a single control rod I35, thesingle shutter I 33 at the top having a control rod I36.

In order to provide clearance for the usual flange or upstanding wall atone side of a compositors tray it is necessary that a chute from whichtype characters fall into the tray should terminate some distancethereabove. In order, so to speak, to fill in the gap between the top ofthe tray and the lower end of the chute there is provided a deviceresembling a bottomless tray which is placed in position above the trayto constitute upward extensions of all the walls thereof, thuseifectively preventing any jerking rments of difierent sizes some of thewalls of the device will be extended downwardly to divide the largercompartments of the tray proper temporarily into separate compartments,thus eiTectively preventing any possible jerking of piled up charactersfrom one compartment into another, and also ensuring even or uniformfilling of the larger compartments. This is illustrated by Figures 14and 15 of the drawings, of which Figure 14 shows a tray in plan andFigure 15 in sectional view on the line i5-I5 of Fig ure 14 with thedevice just mentioned in position thereon. As will be seen the tray haslarge and small compartments I5I, I52, and compartments I53 ofintermediate size. In Figure 15 the usual upstanding flange at one sideof the tray is indicated at I54 and the bottomless tray device at 55. Itwill be seen that this device I55 extends over the whole of thecompositors tray and is flush at its upper surface. Some of thepartitions or compartment walls I56 constitute simply upward extensionsof the compartment walls I5! of the tray, whilst other compartment wallsI58 of the device extend downwardly into the large compartments 55! ofthe tray to divide them temporarily into compartments of smaller size.

Although in all the cases described use is made of the pneumatic type ofautomatic control common in machines of the kind to which the inventionrelates, it will be apparent that ,other forms of control may beemployed. For example, the various operations or movements of themechanism according to the invention may be brought about automaticallyas a result of electric circuits beingbroken or completed instead of bythe open ends of air pipes being covered or uncovered by a travellingpaper strip which latter in such case may carry Contact pieces or stripsfor co-operation with fixed contacts instead of being formed withapertures.

A machine according to claim 10 wherein a supply of air underpressure is normally open to said valves controlling passage of air tothe pneumatic cylinders and also to a further valve controlling thepassage of air to a valve chest and which comprises a first and secondpneumatic plunger adapted to impart rocking motion to said levers toretract said stop and open said valves controlling the passage of air tosaid cylinders, and air lines controlled by valves in said valve chestcommunicating with said pneumatic plungers; the arrangement being suchthat to operate either of said plungers the valve controlling theadmission of air to the valve chest must be open and the valve in thevalve chest controlling the air line. to said plunger must be open.

12. The combination with a type casting machine of the kind referred tofor making type castings presenting a plurality of different characters,each casting presenting a. single character, which machine includespneumatic control means comprising a plurality of air lines controllableto selectively determine the character presented by a casting dischargedfrom said machine, of means for effecting relative movement between acompositors tray and a chute adapted to deliver castings discharged fromsaid machine into said tray, said means comprising air pipes connectedto said air lines and communicating with mechanism operable to effectsaid relative movement, so that operation of said pneumatic controlmeans to determine the character of a casting discharged from saidmachine also effects a relative movement between said compositcrs trayand chute according to the character presented by the castingsselectively determined by operation of said pneumatic control means.

13. Apparatus according to claim 1, wherein a bottomless tray isinterposed between said compositors tray and said machine, said trayhaving compartments at least some of which register with compartments ofsaid compositors tray and being adapted to promote the retention of saidI- castings in the compartments of said compositors tray.
